` o all 'whom it may concern:

Be it known that I, ERNEST Tnvnvmnnorr, u citizen of the United States, residing at Elkhart, in thecounty of Elkhart and State of Indiana, have invented certain new and useful Improvements in Radiator-Caps, of which the following is a specification.

My invention relates to improvements in radiators for cooling internal combustion engines, and has for its object the provision of a radiator cap which may bo readily and quickly attached and detached, and which is provided with an opening for the' radiator which will permit of the rapid filling thereof.

Other objects of the invention are to provide a. radiator cap which may be so quickly handled in tlre application or removal thereof, that practically no difficulty is had in handling the sume when highly heated, the facility -with which same muy be handled thus tending to promote :i more frequent '1nspection or' the water supply, which is more or less neglected under circumstances malring the inspection more difficult. more, as the radiators are usually filled with water carried in a container, such as a bucket or can, I so form the radiator opening that the contents of the container may be more quickly em tied than is possible with the conventiona round opening.

With the above and other objects in view,

the invention in its preferred form #t etails' will be described in the lfollowi specification, reference being had particularly to the accompanying drnwings,"'ih whichz- Figure 1 is: a view of a radiator of my invention.

Fig. 2 is a longitudinal sectional view partly in elevation of the removable cnp.

Fig. 3 is n, longitudinal sectional view ot thc structure forming tho opening,r into the radiator.

Fig. 4 is a top'or plan view of the assembly.

By referring to'the drawings, it will bc fragmentary perspective showingr the application l neon that the opening for the radiator 1,

consists of un opstanding flange or collar 2, which is elliptical in form, so 'that the same will have a considerable greater dimen- .sion in length than in width, one olx the objects of which is: to permit a greater flow of water to enter through the opening frpm Furthcrtho lia ngo n container than is possible through a round opening having ,the same area, flue to the fact that in pouring from a container the stream spreads flat, as is well understood, the volume of flow, without spilling, being" limited by the distance between the opposing walls of the openin In this respect it is assumed, of course, t at the container is held close to or rests upon the flange form` lng the opening, as is the usual practice.

Af' illustrated, the flange 2, which is formed of any suitable metal, is bent inwardly upon itself, as at 3 its edge 4 termi noting short olf thelower edge ot' the flange, said edge 4 being provided with oppositely disposed notches 5, for a purpose presently explained.

Adapted to rest upon the upper edge of the flange 2, is a detachable cap 6 having a body portion 7, which conforms in plan with` the shape of the liungc 2, and provided with n downwardly projecting marginal flange adapted to overlap the outer inurginnl edge of the flange 2 when the cap is resling on the lutter, as shown in Fig. 1. The cap is provided with a centrally disposed andl inwardly projecting cylindrical housing l), enti rely open at its upper end und closed at its lower end. A knol lll, provided with u boss ll on its under side and daptcd to partially project into the housh is provided with u stem 12 of a length i rojoct from the boss through un aperturc lil of which sli-ni there is lixcd u catch or lockiup,r har' I4. interposed between the boss ll and the ond of the housing El, und encircling the stein. 12, is a helical spring 15 tonsioncd lo nornnllly hohl the locking har against the und wall of the housing. In applying tho cap to the flange 2, the knoll lll is dopoogsod with thc locking liur (lisposrd lengthwise of lho cap, :is `ehown in Fig. 2, :ind given n hull' turn to lli-ing the endsl ll ol' lluI locking har in engagement with lheopposiloly disposi-d notches 5 of 2., when the knol is released and tho action olthe spring servos to yidldingly hold thc. lmr in locking engagement with sind notches. oupn slight downward pirs'surc on the lcnolwnjld nl., tho suino lime giving suini :l turn inijloclcs (he cap, when tlusumo, muy llo lit'lod l'rorn ils scat. 'lho rapidity witi which the up muy he locked `and unlocked 'lo unlock and remove thc forms the salient feature of the invention, es the sinne muy he handled when highly heut ed without danger of receiving burns in the handling, nul distinguished from the greater amountof mnnipnlntion necessary in the removal of n cup hnvinr e screw-- threaded connection w ith the rn iator, with the attendant difliculty of handling u highly heated cup;

While the foregoing is the preferred form of my invention, I (le-Hire it to he nn-v derstood that l do not limitJ myself to the precise structure shown ind ,lentrilied, its it 'is obvious that thel sume muy he variously modified Without departing from the spirit of the invention.

It will be noted from the foregoing description, taken in connection with the d ruwings, that the improved radiator cap is positively locked in place by the engagement of the locking, bar in the notches 5, und hence, when once secured, the separation of the parte is not possible under any vibrations" or jars to'whieh the vehicle muy be subjected. Furthermore, the formation of 4the 'iimge 2 is, such as to-providr en effective strengthening, while at the same time perinittin r e simple formation of the notches 5, in t uit seid notches nre provided by cntting the edge of 'the materiel hei'ore the sinne is formed 1n the return hond to 1ness of materiel sitio'n the slp is free, und it Willi he at oneenppnrent that thisa muteriliy facilitates the :apnic-ation und removal of the oep.
